Fuel system issues

He's posted step by step what he did. He went to a steeper gear and started shootin ducks. That aint ignition. That's fuel. He even has said he fattened it up and it helped.
I hear ya. Maybe the steeper gear was a coincidence? Extra fuel can help cover a ignition prob too. I hate to see a mystery problem, but it's how we learn.

Didn't mean to over-step my bounds on the full name mention. I shoulda kept out of that part... I was just thinking (yikes) if Mark's full name shouldn't be mentioned, you could get it edited out quicker.

I can't tell now, ignition or fuel. Oh btw, your distributor spinning to 8900 rpm w/o a breakup; A running engine will be harder on an ignition. Cylinder pressure for the most part, and also heat will cause a few ducks to be killed. (I'm 52 and that's the only way I ever heard those back fires described! lol!)

Keep us updated.
